What feature is most often found with patients with a
splenectomy on a Wright's stained blood smear? -
Answer-Howell-Jolly bodies
Patients with antibody to the following antigen are immune
to Hepatitis B: - Answer-Surface antigen (HbSAg)
Which two of the following tests are helpful for
documenting previous Streptococcal throat and skin
infections: - Answer-ASO titer and Anti-DNase B
In mass spectrometry, the "appearance potential" is
defined as the: - Answer-Minimum energy required for the
appearance of a particular fragment ion in mass spectrum
What is generally accepted as the lower threshold value
for semen pH from fertile males? - Answer-7.2
,2|Page
Coulometry: - Answer-An automated method for
measuring chloride which generates silver ions in the
reaction
Erythroleukemia: - Answer-Also known as Acute
Myelogenous Leukemia type M6. This type is associated
with either the presence of both erythroid and myeloid
precursors OR strictly erythroid precursors.
Myelomonocytic leukemia - Answer-Is associated with an
increase in myeloid and monocytic cell precursors, but not
red blood cell precursors
Species that are Lysine (+), arginine (=) and ornithine (+):
- Answer-Enterobacter aerogenes, Edwardsiella species
and most Serratia species
Lysine reaction for all Citrobacter: - Answer-Negative
Key identifying characteristic for Pantoa (Enterobacter)
agglomerans: - Answer-negative reactions for the three
,3|Page
decarboxylases commonly tested ( Lysine, arginine and
ornithine)
Which organism is MOST likely responsible for septic
reactions associated with Red Blood Cell transfusions? -
Answer-Yersina entercolitica is most likely responsible for
septic reactions in transfusions of Red Blood Cells. This
organism is usually acquired by ingestion of contaminated
food and causes mild symptoms of abdominal pain and
diarrhea. Growth of Y. entercolitica is enhanced in iron-rich
environments such as red cell components.
Gaucher's disease - Answer-The most common lysosomal
storage disease caused by insufficient activity of the
lysosomal enzyme glucocerebrosidase that leads to the
deposition of glucocerebroside in cells of the macrophage-
monocyte system.
Diseases associated with dysfunctions of
polymorphonuclear neutrophils (PMNs) - Answer-Chediak-
Higashi syndrome (CH), Chronic granulomatous disease
(CGD), Myeloperoxidase deficiency (MPO)
, 4|Page
Nephrotic Syndrome: - Answer-Caused by damage to the
kidneys, especially the basement membrane of the
glomerulus; which causes abnormal excretion of protein
and red blood cells in the urine. Fats are also present in
the urine in most cases. A foamy appearance of the urine
is a key characteristic of this condition.
Clinical symptoms include:
Swelling
Weight gain from fluid retention
Poor appetite
High blood pressure
Key Biochemical reactions for Enterobacteriaceae: -
Answer-The key biochemical reactions by which the family
Enterobacteriaceae can be identified include fermentation
of carbohydrates, reduction of nitrates to nitrites and the
absence of cytochrome oxidase activity.
